I have an old version of Cleansweep 3.0 from 1997. What is needed to upgrade to one that supports Windows 7?
This is an application which was used to clean your computer from junk files and anything that is related to this job. Windows 7 was not designed to run programs like these because they are too old and there is no update released to make it compatible for Windows 7. In this case I recommend using something that is compatible and available for this operating system. CCleaner does its job very well regarding computer cleaning.
